A peculair feature often observed within the sodium diethylhexylsulfosuccinate (AOT)—water-—oil phase diagram is an isolated two-phase island, when water in oil (w/o) microemulsions are formed at low temperatures. In this work, the influece of the hydrolysis products of AOT, namely monoester and alcohol, on the phase behavior has been modeled by adding SDS and octanol to (H2O/NaCl)—decane—AOT systems. Addition of small amounts of either compound, frequently present as impurities in AOT, leads to drastic shifts in the mean temperature of the three-phase regions in opposite directions. In particular, addition of octanol changes the shape of the one-phase region adjacent to the three-phase body. [ABSTRACT FROM AUTHOR] |
